SPECIFICATION formingpart of Letters Patent No. 697,760, dated April 15,1902.

Application filed July 29,1901. Serial No. 70,069. (No model.)

To (tZZ whom it may concern:

Be it known that I, HENRY C. VVARFEL, a

citizen of the United States, residing at Philipsburg, in the county ofCenter and State of Pennsylvania, have invented certain new and usefulImprovements in W'indow-Oleaners, of which the following is aspecification.

The window-cleaning device which forms the subject of this patent isknown as the handled fou ntain-washer, in which a washing-strip and adrying-strip are employed, and my improvement is directed to a novelmeans whereby the washing-strip is secured to its holder and theconstruction whereby the holder is secured to the water-chamber, as IWill particularly point out in the claims appended hereto and asillustrated in the accompanying drawings, in which Figure 1 shows inperspective the handled water-chamberhavingmyimprovement. Fig. 2 is atransverse section of the same. Fig. 3 shows the novel holding devicefor the washing-strip, which itself is not shown. Fig. 4 is across-section showing the manner of securingthe washing-strip within itsholder and the manner of securing the latter to the Water-chamber. Fig.5 shows a like view of the holder for the washing-strip with its sidewalls indented to spread the cleaning-surface of the strip and is aslight modification.

The water-chamber is a casing preferably of approximately triangularcross-section, with a handle standing from one of its angles 1nediatelyof its length. At the other angle of the base of the triangle isfastened a drierstrip 1, preferably of rubber. At one end of the chamberis the cap-covered opening 2 for supplyingthewater-chamber. Thesidewalls of the water-chamber 3form a comparatively narrow oblong opening,and to the edges of these walls at this opening is secured the holder 4,as a separate part for a fabric washing-strip 5, and it is theconstruction of this separate holding and binder part wherein myimprovement resides and which lessens the cost of manufacture and givesconvenience for removing, reversing, and replacing thefeltwashing-strip. This separate holder part is trough-shaped incross-section, the edges of its open side terminating in return-bends 66, standing obliquely toward each other, so as to form internal lipsadapted to engage the sides of the felt washing-strip and acting thereoneach with a binder function, each lip or flange thereby caused to biteinto the felt by reason of standing in oblique lapping relation to theinner side walls of the holder. In this biting function each lip orflange forms a detent to prevent the felt strip from being pulled orfrom working out in using it under pressure upon the window. These lipsor flanges are preferably the length of the holder and formed integraltherewith, and over them it is easy to draw the washing-strip endwiseinto and through the holder and to remove it therefrom in the same way.At its closed side this holder is fastened directly to the edges of thechamber-casing,at the oblong opening thereof, so as to close saidopening. This fastening is by solder, and to reinforce it and render thesecuring of the holder strong and durable against the pressure put on itby the rubbing action upon the window the case edges may be sunk inchannels or grooves 7 7, formed in the closed side of the holder alongits corners or angles, so that in applying the solder to the channels orgrooves it will take better hold on both sides of the case edges andgive a better and true seating of the holder upon the edges of thewater-chamber. Holes 8 are made along the closed side of the holder,through which the water from the chamber passes to keep the fabricWashing-strip wet.

In Fig. 5 the sides of the holder are shown indented at 9 9, which actsto slightly compress the inturned lips or flanges of the holder upon thefelt strip, and thereby to cause its projecting rubbing part to spreaderbe expanded transversely to give a better cleaningsurface.

I claim 1. In a window-cleaner, a washing strip holder consisting of atrough-shaped binder, the edges of its open side formed each with areturn-bend standing obliquely toward each other within and toward thebottom of the trough to engage and form detents for the washing-stripwithin the holder.

gage and form detents for a fabric washingstrip bound Within the holder.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY O. WARFEL.
